  • Publication number: 20190343957
    Abstract: Disclosed are methods of making oral pharmaceutical compositions that contain substantially crush-resistant drug-containing microparticles. The microparticles may contain an active pharmaceutical agent, a polymer and a plasticizer. The microparticles may be uncoated (so as to impart an immediate release profile) or coated so as to impart an extended-release (ER), delayed release (DR) or delayed-extended release (DER) profile. One or more of the populations of microparticles may be coated with a taste-masking composition. The methods may produce oral compositions such as orally disintegrating tablets that contain one or more these types of microparticles in order to further customize the release profile. Also disclosed are the oral compositions, per se, and methods of using same for their intended purposes.
